MACHINE FOR CLEANING AND SEPARATING CRANBERRIES.

SPECIFICATION forming part o Letters Patent No. 377,667,1dated February 7, 1888. Application filed vlauuary 6, 1887. Serial No. 223,605. (No model.)

To @ZZ whom it may concern:

Be it known that I, HALE GHADWICK, a citizen of the United States, residing at Penacook, in the county of Merrimac and State of New Hampshire, have invented a new and useful Machine for Cleaning and Separating Cranberries, of which the following is a specification. v

The object of this invention is to provide a machinel fo'r cleaning and separating the dirt from cranberries, which may be Y driven by power or by hand; and the invention consists in the combination of the vibratory and sta tionary screen, a feed or carryingV wheel, and various other mechanism, all of which will be hereinafter fully explained and pointed out in this specification and appendedclaims and be clearly illustrated in the accompanying drawings, forming an inseparable part thereof, of which- Figure 1 is a vertical sectional elevation of the machine, Fig. 2 being a general plan View of same. Fig. 3 is a detached elevation of the drive-wheel, and Fig. 4 represents a portion of the machine in side elevation.

Similar letters indicate corresponding parts.

A represents the frame supporting the inclined chute B, whose sides maybe vertical and parallel one with the other, except at its mouth, which may be contracted or narrowed some by the pieces b b, in order to check the discharge of the berries, for a purpose to be hereinafter described.

' A frame-work, A', rising from the top of the inclined chute B, supports a hopper, C, for receiving the berries, which fall thence into a vibratory screen, D, having exible supports E at one end and a'supporting-bar, d, either end of which rests in a slot formed in the vertical sides of the inclined chute B.

I would have' it understood that I do not confine myself to any particular mechanism for agitating this screen D, as various devices may be used for this purpose, one simple means being shown in the drawings, consisting of a lever, F, fulcrumed to a stand, G, which may be screwed to the inclined chute B, as shown, one end of this lever F being pivoted at f to a v projecting end of the bar d, -and the opposite end, f', is held in contact with the drive-wheel H by means of the spring G', which may besecured to the chute B, as shown in Figs. 2 and 4. This drive-wheel I:I is provided with pro jectious h on one side, which may be beveled, as shown best in Fig. 2, and the endf of the lever F in riding over these ridges or projections h, which should be located at regular intervals around the wheel H, causes the screen D to shake laterally and allow'the berries to Aconnected by the belt K with a pulley, L,

mounted upon the shaft M, which is hung in bearings m, carrying between said bearings the cylinder N, having at regular intervals upon` its periphery transverse slats or float-s a. This cylinder N is designed to rotate inthe direction indicated bythe arrow in Fig. l.

The chute B may be provided with a screenbottom, B', for the entire distance from said cylinder to the lower end thereof; or said screenbottom B may extend only from the crossbeam b to the beam 152, and a narrow space, B3, may be left between the said cross-beam b2 and the remainder of the bottom of said chute,

which may be solid and Without openings or perforations of .any kind. This construction I consider preferable. l

, rIhe screenbottom B' may be composed of rods running longitudinally and fastened in some convenient and firm manner to the crossbeams b b2,- or a cast grate may span the distance between the two beams with good results. The bottom D in the vibratory screen D is also composed of rods similar to the rods used for the bott-om B of the chute B; or said bottom D may be composed of a cast grate, as described above, for use in said chute B.

The rotation of the drive-wheel H by reason of the belt-pulleys J L and belt K revolves the cylinder N in the direction indicated by the arrow in` Fig. l, and the screen D, vibrated in the manner previously described, discharges the berries upon said cylinder N, the imperi fect berries and dirt, stems, Stoa, being carried over to the reariby the oats or slats n and dropped, while the perfect berries bound off IOO of the said cylinder and fall upon the screenbottom B of the chute B.

During the above-described operation any stems and dirt or imperfect berries which escape, being carried or deposited to the rear by the cylinder N, pass through the screenbottom B; or, in any event, the refuse matter will, if it has escaped the cylinder N and screen B', drop through the transverse opening or slot B3 before the final discharge or passage of the perfect vberries through the mouth of the chute B.

Having described my improvements, what I claim as my invention is- 1. The combination of a receiving-hopper, a vibratory s'crecnlocated directly under the same, a rotary cylinder, and radial transverse iloats or slats arranged at regular intervals thereon, an inclined chute having a screen or grated bottom adapted to receive the perfect berries from said cylinder, and suitable operating mechanism for the vibratory screen and rotary cylinder, substantially as and for the purpose set forth.

2. The combination of a receiving-hopper, an inclined vibratory screen located directly under the same, a rotary cylinder, and radial iioats or slats secured at regular intervals thereon, an inclined chute adapted to receive the perfect berries from said cylinder, having a screen forming a portion of the bottom thereof, and provided at the lower end of said screen with a transverse opening or slot, and operating mechanism, substantially as and for the purpose specified.

3. In a machine for separating cranberries, the combination, with a hopper, a horizontally-vibratory screen, and an inclined chute, of a rotary cylinder located between said screen and chute revolving toward the former, and having radial slats for carrying away the im* perfect berries and other refuse, substantially as described.
